Except you don't normally "give" I2C devices addresses (unless you're making them yourself) - you usually are able to select between a couple of addresses using special pins on the I2C devices. If you can't select different addresses then you have the option of an "I2C multiplexer" to select between them. | |

Thanks for your help! | |
